Notes:
1. Supply fan performance table includes internal resistance of rooftop. For total static pressure determination, system external static must be added to
appropriate component static pressure drops, (evaporator coil, filters, optional economizer, optional heating system, optional roof curb).
2. The pressure drops from the supply fan to the space should not exceed 2.5” wg (620.9 Pa) positive.
3. Max cfm for 33 ton unit 6825 L/s, 42 ton -7860 L/s
4. Max motor hp for 33 ton unit-11.2 kW (15 hp), 42 ton 14.9 kW (20 hp)
